Abstract: An augmented reality system can include a headset frame wearable by a user. A window disposed in or on the headset frame can include adjacent first and second window regions. When the headset frame is worn by the user, a field of view of an eye of the user can extend through at least part of the first window region. A camera can be disposed in or on the headset frame. When the headset frame is worn by the user, the camera can have a field of view that is directed away from the user and through the second window region. A controllably dimmable filter can be located adjacent to the window in the field of view of the eye and the field of view of the camera. The controllably dimmable filter can have a controllable opacity that determines a visibility of the camera through the second window region.

Abstract: Eyewear including a dipole antenna having a first leg and a second leg, wherein the first leg includes at least a portion of a battery, such as a conductive case of the battery. An antenna feed is coupled to the dipole antenna between the second leg and the battery. The second leg may comprise a flexible printed circuit (FPC), and the second leg is an active leg. The second leg has a first portion and a second portion. The first portion and the second portion may have the same physical length. The first portion may be dielectrically loaded with a high permittivity loaded material, and the second portion may be dielectrically loaded with a low permittivity loaded material.

Abstract: A shield can for an electronic eyewear device is described that reduces RF signals emanating from the electronic eyewear device. The shield can is attached to a ground plate of the electronic eyewear device using leaf springs on a side of the shield can. The leaf springs do not add to the stack-up thickness of the shield can assembly and provide a balanced force against the ground plate. The shield can is attached to a printed circuit board and encompasses radio frequency (RF) electronic components to prevent RF signals emanating from the RF electronic components. The leaf springs have a pair of fingers providing the balanced mechanical point force. A conductive pressure sensitive adhesive is also provided to secure a top surface of the shield can to the ground plate along with a thermal paste.

Abstract: Eyewear having a frame, a hinge, and a hyperextendable temple having a flexible printed circuit (FPC) including service loops. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. A first service loop allows extension of the FPC when the temple rotates about the hinge, and a second service loop allows the temple to be radially extended away from the hinge.

Abstract: A device includes a frame and a waveguide. The waveguide has a first end fixedly coupled to a first portion of the frame, and a second end proximal to a second portion of the frame and detached from the frame. When the frame deforms to displace the first portion and the second portion relative to each other, the second end of the waveguide is not displaced relative to the first end of the waveguide as a result of the frame deforming.

Abstract: A slide switch with an elastomer web for eliminating slide backlash and rattle. The elastomer web is disposed in the motion path of a mechanical slider and biases the slider to contact a switch nub. The biased slider eliminates a loose translational motion of the mechanical slider and therefore a user's perception of loose motion or backlash when actuating the switch. The elastomer web improves the user's perception of the mechanical slider's quality. Additionally, the elastomer web allows for larger assembly tolerances between the mechanical slider and the switch nub. An increased assembly tolerance improves yield for mechanical parts and reduces the cost of manufacturing.

Abstract: Eyewear hinge assemblies for eyewear that connect temples to a frame. The hinge assemblies include hinge elements that are attached to the temples in an extended state, which stores an initial amount of energy or pre-load. The pre-load biases the temples inwardly and toward one another. After the temples are placed on the user's head, stored energy in the hinge elements can be released as the hinge elements exhibit elastic recoil. This causes the temples to grip the sides of the user's head in a snug and comfortable fit. The hinge assemblies have compact designs with material properties that provide comfortable closing forces while aiding in the reduction of electromagnetic noise from electrical subsystems in the eyewear.

Abstract: A housing assembly for an electronics-enabled device includes a housing wall having parallel inner and outer faces, with a hinge base affixed through the wall. The hinge base has a shank extending through the wall and a joint mount exterior to the housing for hingedly mounting an external component. An anchor plate inside the housing is welded to the shank, preventing axial withdrawal of the hinge base by obstruction against the inner face. The welded connection rotationally keys the anchor plate to the hinge base. The assembly enables integration of electronics components mounted on the anchor plate, which can serve as a thermal conductor between heat-generating components and an external heatsink via the hinge base. In electronics-enabled eyewear, the hinge base provides hinged connection of a temple to an eyewear frame. Manufacturing involves locating the hinge base and anchor plate, translationally fastening them together threadedly, and spot-welding for rotational keying.
